-LRB- CNN -RRB- -- An arrest in which several punches were thrown has triggered an accusation of brutality against Pittsburgh , Pennsylvania , police from the mother of the 18-year-old honor student who was taken into custody .

Police , in a criminal complaint on the incident , say `` closed fist strikes '' were used by the undercover police officers , but only to subdue the teenager as he tried to get away .

His mother said she plans to file a civil rights claim against the officers .

Terez Miles said her son , Jordan Miles , who is black , thought his life was in jeopardy when three white men jumped out of a car on the night of January 11 as he walked not far from his home .

`` My son tried to run thinking his life was in jeopardy , '' Terez Miles said . `` He made three steps before he slipped and fell . '' After that , she said , the police used a stun gun and beat him , pulling out a chunk of his hair .

The criminal complaint says the officers , considering Jordan Miles ' appearance suspicious , got out of the car and identified themselves as police . He tried to flee , fell , and then struggled to escape .

The officers `` delivered 2-3 closed fist strikes to Miles ' head/face with still no effect , '' and then a `` knee strike to Miles ' head causing him to momentarily stop resisting , '' so that he could be handcuffed , the document says .

Miles ' mother said the officers did not identify themselves as police to her son , a viola player and student at the city 's Creative and Performing Arts High School .

The complaint says the police officers believed Miles was engaged in criminal activity and possibly armed with a `` large heavy object . '' The object turned out to be a bottle of Mountain Dew .

Miles was charged with aggravated assault , loitering , resisting arrest and escape .

A hearing in the case was scheduled for Thursday , but it was unclear whether the officers involved showed up , said Miles ' attorney , Kerry Lewis . The judge postponed the case until February 18 .

Pittsburgh Mayor Luke Ravenstahl is `` taking this very seriously , '' said his press secretary , Joanna Doven . `` The case is being investigated , he 's closely monitoring it . He 's met with the chief . ''

The three officers were taken off plainclothes duty and were back in uniform , she said .

Terez Miles contends the officers used too much force .

`` My son is 150 pounds and 5-foot-6 . There 's no need for this degree of violence and brutality for someone of this stature , '' she said .

Lewis said Jordan Miles has no criminal record .
